Chromstar 2000 Series Antenna Pre-Amplifiers
Features 75 ohm input for convenience and easier installation. Universal housing can be used with any off-air TV antenna. Made of high impact ABS material, mast mounted for easy installation. Flexible polyethylene boot covers on 75 ohm. Zinc-plated steel hardware; all mounting hardware included.
Selectable FM trap reduces FM signals (88-108 MHz) -15 dB to prevent overload, tunable FM trap reduces a 3 MHz band width by -12 dB. Both adjustable — switchable without opening the housing.
Transistor burn-out virtually eliminated with specialized circuitry featuring fast recovery diode that protects against lightning-caused pulses. Operating temperatures -40° to +140° F. 117 VAC UL and CSA approved power supply is included. (Does not include F-connectors.)
NOTE: Preamplifiers and/or amplifiers only amplify the signal your antenna receives. They cannot extend the receiving range of an antenna or help pull in signal. Also, DO NOT use the higher gain models within 35 miles of your transmitters.

Recent Review: Irishboy - Gulfport, rt MS - 3/28/2013 Power and FM Trap are Notable
Power and FM Trap are Notable Irishboy - Gulfport, rt MS - 3/28/2013 I use this preamp to provide amplified signal totwo receivers. I have actually purchased 4 Winegard preamps for myself and others and they are all still working great.
Good product with short life georgia87 - Jefferson, rson GA - 3/28/2013 I installed the 8780 and got excellent performance drawing in channels from Atlanta (55+ miles) South Carolina and North Carolina. However it died after 9 months of use. The company says it only has a 90 day warranty. Going to try a different company.
